SPECIFICATION `forming part of Letters Patent No. 717,374, dated December 30, 1902.

k u Application led February 2l, 1902. Serial No. 95,087. (No model.)

To LZZ whom, t may concern:

Be it known that I, ARTHUR C. FERGUSON,

a citizen of the United States, residing atu in which the type-bar support is mounted above the carriage.

The invention has for an object to provide an improved construction of type-bar support having aliniug and locking recesses for the type-bars when the sameA are placed into printing position.

A further object of the invention is to provide a construction whereby the diametrical center of the type-bar support is above the platen carried by the paper-carriage.

Another object of the invention is to provide a key-lever bearing directly upon the type-bar and provided with means for operating an escapement mechanism and aribbonfeed mechanism as the bars are depressed for the printing operation.

A further vobject is to provide an improved,

construction of typeebar supportwhich is pivotally mounted 4at one side and capableof reciprocation at an angle to its pivot transversely of the carriage beneath `the same. Other and further objects and advantages of the invention will be hereinafter set forth and the novel features thereof defined by the appended claims. p In the drawings, Figure l is a plan of the invention. Fig. 2 isavertical section on the line 2 2 of Fig. 1. Fig. 3 is adetail perspective of the type-bar support and its mounting. Fig.`4 is a detail end View of the shifting means for said support,and Fig. 5 is a detail plan of theescapement mechanism.

Like letters of reference refer to like parts throughout the several figures of the draw'- ings.

The letter A refers tothe base, which may be of any desired construction or configuration and provided at the front with opposite standards A', upon which the type-bar support B is mounted. At the rear of the base a carriage Ois mounted to reciprocate thereon and is provided `with a platen C and guard O2 at `the rear. This carriage is provided With a rack-'bar O5, adapted to engage suitable escapement mechanism D, provided with dogs of ordinary construction, which mechanism is pivotally mounted upon the base at D' and provided with a lever-arm D2, extending to the front of the machine beyond the type-bar support B. The platen is adapted to be rotated by ahandle O4 at one end and the feed- Vpawl O5 at the opposite end engaginga ratchet C5. The carriage is actuated by means of the winding-drum O5, of ordinary construction, having the spring O8 connected thereto and a cord O9, extending from the periphery ofthe drum to the carriage, as shown by dotted lines in Fig. l. Y

The type-bar support is provided at opposite sides with supporting-arms B', one of which is pivotally mounted upon a pin A2 by means of the lug B2, and at the opposite side a lug B3 forms a hook extending over the pin A2 from the standard A. A suitable catch B4 may be used with this hook to prevent a vertical movement of the support. This supportis provided with a series of recesses or grooves B5 upon its upper surface, extending radially fromthe center of the support, and upon the periphery lugs B5 are provided, betweenwhich the type-bars E are mounted, by means of a continuous pivoting rod E', adapted to fit grooves B7, formed upon the periphery of the lugs BG. In the illustration of the invention type E2 have been omitted from most of the bars and keys from 'the le.- vers in ordernot to obscure the other parts.

Beneath the grooves or recesses B5 cases or shells E3 are radially disposed opposite openings BS in the support, and connected to the inner end of 'these cases are coiled springs E4, having their outer end pivotally secured at E5 to the lower end of the type-bar E, thus providing means for restoring the bars to an elevated position. The support B is adapted to be shifted laterally of the carriage and at a right angle to its pivot B2 by means of a Akey-lever F, having at its lower end F a universal joint connecting with`a link F2, pivotally secured at its opposite end to the support B, as shown in Fig. 4:. Each of the type E2 is supplied with two characters-for IOO instance, capitals and small characters-so that the lateral shifting will permit the use of another character 'from that used when the support is in its normal position.

For the purpose of depressing the type-bars E a series of key-levers G are provided, one in alinement with each bar and each provided with a key G. These levers are pivoted at their outer ends to a fixed ring or support G2, carried from the type-support B by means of an arm G3, (see Fig. 2,) and the upward movement of the lever G is limited by means of an annular stop G4, supported from the support G2 by means of lugs G5. The inner ends of the levers G are bifurcated, as shown at G6, and t over the type-bars E. The escapement mechanism D is connected at its for- Wardend D2 with a universal bail or loop H, extending beneath the key-levers,and pivoted at the rear by means of the arms I-I' upon the support G2. The depression of one of the key-levers carries downward the loop II and the outer end of the lever D2 to operate the escapement mechanism for feeding the carriage. This loop is provided at the front with a key H2 for depressing the loop to space when the key-levers are not used. The ribbon mechanism comprises a spool I, carried by hangers I', extending downward from the rear of the support G2, and a spool I2, supported by hangers I3, depending from the front of the support G2, as shown in Fig. 2. The oscillating loop I-I of the escapement mechanism is provided with a depending arm I4, passing through a guide-lug I5 from the hangers I3 and provided with a spring-pressed pawl I6, adapted to engage a ratchet I7, carried by the journalof the spool I2, so thatin the ascending movement of the loop H the spool is rotated to feed the ribbon after the type have left the printing position upon the platen. A ribbon I8 passes from one spool to the other and is supported in any desired manner-for instance,

' by means of a rod I2-so as to carry it above the platen and beneath the type-bar support.

From the foregoing description it will be seen that a depression of the key-levers G will carry downward the type-bar and type, placing the spring E3 under tension and also depressing the loop H to operate the escapement mechanism. When the pressure is removed from the key G', the spring E4 restores the type-bars and key-levers to their initial position in contact with the guard G4, while the loop H is raised by the flat restoringspring D2, extending from the base to the escapement mechanism, and the ribbon-spool I2 thereby rotated. It will be seen that the type-barsupport provides recesses for locking each of the'type-bars in positive alinement when depressed for printing, and this support is so mounted that all of the parts carried thereby may be lifted from the platen by means of the pivot B2 whenever desired and shifted laterally of the platen when it is desired to use other characters. It will also be observed that this support is mounted so that its diametrc center, or the center of the type to be used, is directly above the platen C' of the carriage. This construction of type- Writer provides a simple and economicallyconstructed device in which the type-bars are positively depressed by the key-levers into their printing position, and the depressing thereof actuates the escapement and ribbon-feed mechanisms, whereby an accurate alinement is secured and a rapid operation of the keys permitted, thus effecting a machine which can be very cheaply constructed and perform the most efficient character of Work.

It will be obvious that changes maybe made in the details of construction and configuration of the several parts Without departing from the spirit of the invention as defined by the claims.

Having described my invention and set forth its merits, what I claim, and desire to secure by Letters Patent, is
